No, not really. I feel like you're looking for a lot of absolute answers where there are none. Truth is, there isn't a single "best" headphone that we can recommend you, and just those numbers can't tell you how the headphones are going to sound. At the end of the day, you're just going to have to listen to some headphones to see if you like them or not for your music and preferences.
EDIT: Also, in your consideration of closed v. open, where and when do you plan to use your headphones? Are you ever going to use them when you're out and about? Or will it just be at home?
